Title: Hologram recording medium
Inventor: YAGI IKUTAKE
IPC: G03C1/725
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To reduce a problem of hologram disappearance even in the case of being preserved in a dark place and increase photosensitivity of refraction index distribution formation by usina a monocrystal containing europium and cerium as impurities in strontium barium niobic acid(SBN). SOLUTION: In a recording medium in a hologram recording system, a monocrystal containing europium and cerium as impurities in SBN (Srx Ba1-x Nb2 O6 , 0<1<=0.75) is used. As a method of intermixing a small quantity of cerium and europium at the time of monocrystal growth of SBN, there is a method of mixing cerium and europium in raw material at the time of making the SBN monocrystal grow using a pot, for instance. In the case of both cerium and europium being contained in the SBN monocrystal, photosensitivity of refraction index mudulation is heightened in comparison to the case of containing only cerium, and the decay of a refraction index modulation factor at the time of preserving in a dark place at room temperature is delayed, that is, as the recording medium, recording speed becomes fast, and data storage stability is improved.

IPC: B60G17/015
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To reduce damage in amenity as much as possible under bad traveling road characteristics by providing a change device for adjusting a vibration damper and deciding the change of the vibration damper adjustment according to the time elapse of acceleration of practical intervals. SOLUTION: As for a vehicle having an air spring, an output 5 of a block 1 and an output 7 of a block 2 are supplied to a block 3 as an input and a comprehensive damping demand is calculated by changing the damping demand of a structural part according to a bad road characteristic value. An acceleration of practical intervals is summed in a time window forming a starting point and fluctuating so as to remove long-wave components. In this change, the bad road characteristic value sets the optimum conditions to correct the damping demand of the structure part and the direct detection of the damping force or a damper speed under a substitutional condition is eliminated so that the bad road characteristic value is set to the substitutional quantity substituted for the damping force.  That is to say, a large bad road characteristic value expresses a lot of components of the high frequency shaft vibration and large damper speed and damping force are generated.

Title: Variable attenuator
Inventor: KATO AKIRA
IPC: H03H7/25
Filed: 1992-12-02
Abstract: PURPOSE:To easily control an attenuation amount and to save electric power. CONSTITUTION:RF signals outputted from a signal generator 6 are divided into equal halves by the two lines 10 and 11 of an electric distributor 1 and are distributed to two routes (1) and (2). A variable phase shifter 2 is inserted to at least one of the routes (1) and (2) and is provided with variable capacitance diodes 28 and 30 operated in reverse bias. Since a current does not flow into the variable capacitance diodes 28 and 30, the electric power can be saved. Then, the capacitance of the variable capacitance diodes 28 and 30 is changed corresponding to a single control signal Vs and the phase of the inputted RF signals is shifted. Since control can be performed by the single control signal Vs, the control can be facilitated. An electric power synthesizer 3 respectively synthesizes the RF signals through the respective routes (1) and (2). The variable phase shifter 2 makes the respective RF signals compensated corresponding to the phase difference of the RF signals of the respective routes (1) and (2) at the electric power synthesizer 4 and attenuates the level of the synthesized RF signals.
